The previous version of MX-700 was already a very good wireless mouse, even if it not just distinguished by longevity. Logitech has but actually managed nachzulegen again. The general benefits of a wireless optical mouse with charging station I do not want to enumerate again at the site but rather report a few details compared to the MX-700. The laser optics of the MX-1000 is really noticeably better. Even on my clear lacquered wooden table, it is now possible to position the mouse pointer pixel accuracy with slow movements. However, no chance in the MX-700, which is always equal jumped by several pixels. The radio communication has been improved. Here I had the most concerns, but the MX-1000 is a wired mouse in fact to nothing. Delays are no longer noticeable. The MX-1000 is a lithium-ion battery is installed. While holding a charge for several days, but so eliminates the possibility to replace the battery or load externally. In my MX-700, the supplied NiMH battery was broken after a few months, later the charger had contact problems, so I learned to appreciate it, to be able to charge batteries externally. I hope that Logitech has these problems now get in the MX-1000 in the handle. The form has become even more ergonomic. Although the MX-1000 again slightly heavier than the MX-700, it fits comfortably and securely in your hand a right-handed. Disturbing is the fact that the mouse slightly wobbles on the table, as if the bottom had warped. It also requires a little practice, the middle mouse button sure to press without pressing the tilt function from the scroll wheel. The use of Linux is a little more problematic than with the MX-700. While the basic functions (three mouse buttons, scroll wheel) work perfectly, the scroll button upwards acts upon release but as a pressure on the middle mouse button, and the tilt function (scroll left or right) is currently not available. A suitable driver would help, but Logitech does not even support Linux and hopes that the "community" one day will subsequently supply the driver. The setting is disappointing as Linux has established itself on the market. Actually, the mouse has earned five stars. One point deduction, there were then but because of the wobbling and the lack of Linux drivers. PS to answer a common question: no, the mouse can not divert a laser pointer. Actually you can see from the sensor even nothing shine.
